Target only single product page

I assume you mean to use this on a single product’s page, right? If so, try this:

add_action('admin_head', 'wwc_my_custom_css');

function wwc_my_custom_css() {
if (!current_user_can('edit_pages'){
   global $post;
   $isProduct = $post->post_type == 'product'; // use the actual name for product

   if ($isProduct ) {
     echo '<style>
               #mceu_27-body, #wp-content-editor-tools{
                  display:none !important;
               }
          </style>';
     }
  }
}
